> OK, split it down the middle. If you're already a @bob follower when you start following @alice or when @alice un-@s @bob, whichever happens later, then @alice's action has no effect on you. Even if @bob has been hidden from you by @alice's action, it only affects internal-to-twitter links like retweets. If you have a link directly to @bob or his tweet from Google or from an email, you can follow it successfully, and that action removes the hiding effect for you. These extra complications would probably be good for @alice, since it would make it much less obvious to bullies that she had taken this action in the first place. (Yes, if @bob has observant friends, they'll notice eventually, but that's probably OK.)

That could work well enough. :)

Yeah, my main concern was a power user who people wouldn't want to unfollow abusing the feature to silence critics.
